Magnetic resonance (MR) imaging offers a noninvasive method to assess cartilage repair, allowing objective evaluation of the repair tissue and insight into the natural history of cartilage repair procedures. MR imaging allows assessment of the percent fill, signal morphology of the repair tissue, subchondral bone and three-dimensional geometry of the joint. The information gained from MR imaging therefore plays a valuable role in patient follow-up after cartilage repair. This article discusses the MR imaging techniques available for the assessment of articular cartilage, including quantitative imaging techniques that allow assessment of cartilage biochemistry. The MR imaging appearance and assessment of microfracture, autologous chondrocyte implantation, and osteochondral autograft and allograft transplantation is reviewed.
磁共振（MR）成像提供了一种评估软骨修复的非侵入性方法，能够对修复组织进行客观评估，并深入了解软骨修复过程的自然史。MR成像可以评估填充百分比、修复组织的信号形态、软骨下骨以及关节的三维几何结构。因此，从MR成像中获得的信息在软骨修复后的患者随访中发挥着重要作用。本文讨论了可用于评估关节软骨的MR成像技术，包括能够评估软骨生物化学的定量成像技术。本文还综述了微骨折、自体软骨细胞植入、自体骨软骨移植和同种异体骨软骨移植的MR成像表现及评估。
